Japan, Sept. 18 -- KODENSHI CORP has got intellectual property rights for 'OPTICAL SENSOR AND METHOD FOR CONTROLLING OPTICAL SENSOR.' Other related details are as follows:
Application Number: JP,2023-196544
Category (FI): H01H35/00@L,G02B5/22,G02F1/13,505
Stage: PROBLEM TO BE SOLVED: To improve appearance without significantly reducing sensing accuracy in an optical sensor including an optical filter.SOLUTION: An optical sensor includes: a light source emitting light in a predetermined wavelength range toward an object to be detected; a light receiving element detecting light reflected from the object to be detected; an optical filter disposed in front of the light receiving element and selectively transmitting light in the predetermined wavelength range; dimming glass disposed to cover the optical filter and switched between a transparent detectable state and a cloudy standby state when being energized; and a dimming control part switching the energized state of the dimming glass such that the detectable state and the standby state are alternately repeated.SELECTED DRAWING: Figure 2 (Grant)
